Question

Given a sphere with a radius of 2 cm, find its volume to the nearest whole

Answer 1

$\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=2 \end{cases}\implies V=\cfrac{4\pi (2)^3}{3}\implies V=\cfrac{32\pi }{3} \\\\\\ V\approx 33.51032163829112\implies \stackrel{\textit{rounded up}}{V=34}$
